摘　　要：研究了脉冲星的外间隙模型,分析了传统的外间隙模型和新的外间隙模型之间的不同之处.指出脉冲星表面强磁场感应出来的电场虽然很强,沿磁场方向的电场分量几乎为0,但是在外间隙加速区,带电粒子会被加速到相对论能量,产生高能辐射.The pulsar is the rapidly spinning neutron star with strong magnetic field. The study of high-energy radiation from pulsars is helpful for us to understand the physical processes taking place in the pulsar strong magnetic field. This paper studies the outer gap model of pulsars, analyzes the differences between traditional outer gap model and the new one, and points out that the electric field created from the pulsar surface is very strong but the electric field along the magnetic field is almost zero, and charged particles are accelerated to relativistic energy in outer gap resulting in high energy radiation.

关 键 词：脉冲星 外间隙模型 相对论能量 高能辐射
